Change in somatosensory evoked potentials detect an acute arterial stent occlusion in lower extremity during spinal surgery: Case report.

The authors report a case in which an acute thrombosis of a pre-existing arterial stent occurs in a patient's lower extremity during a lumbar spinal fusion surgery. The event was detected by acute changes in somatosensory evoked potentials (SSEPs) which were being monitored during the procedure. The neurophysiology technologist reported a 10 % increased latency and 50 % loss of amplitude in the left posterior tibial nerve recordings.

Atypical ductal hyperplasia on core needle biopsy: Surgical outcomes of 200 consecutive cases from a high-volume breast program.

Atypical ductal hyperplasia (ADH) is an indication for excisional biopsy to rule out occult breast cancer. We analyzed pathological findings on excisional biopsy for ADH diagnosed in a high volume breast center equipped with digital tomosynthesis. Two hundred consecutive patients were diagnosed with ADH on core biopsy with radiographic concordance followed by excisional biopsy.

Atypical lobular hyperplasia on core needle biopsy: contemporary results from a large community hospital breast program.

Purpose: The management of biopsy proven atypical lobular hyperplasia (ALH) is controversial. Although upgrade rates are low, excisional biopsy is often performed to rule out occult breast cancer.

Methods: In this study, we analyzed our experience with excisional biopsy for ALH diagnosed in the digital tomosynthesis era with radiographic concordance in the community hospital setting.
